You can specify exactly how you want your printed text to appear on the label by modify options on the properties panel. Select the text object that you want to modify, you will get the Text properties list.
Stretch: When enabled, the software will resize text to fit within a rectangle of a specified size. This is useful when the data contained in a text object is highly variable in length, but must always fit within a certain area on the label. Program will increase or decrease the font size of the text contents so that it fits within the boundaries of the text object.
If you have this option disabled, the software will print paragraph text within the boundaries of the text object as its font size and alignment.
WordWrap: Specifies whether text displays on a single line or multiple lines within a text object. Available only when you disable the option "Stretch".
